Abstract
U radu je izvršena analiza opterećenja dijelova mehanizma četverotaktnog dizel motora u V izvedbi, snage 720 kW pri brzini vrtnje 1600 o/min. Osnovni opis zadatka dat je u prva dva poglavlja rada. U trećem poglavlju su date karakteristike motora. Kroz četvrto poglavlje date su formule za riješavanje kinematike i dinamike mehanizma, te uravnoteženje masa. Analiza opterećenja je provedena u programskom paketu MS Excel, korištenjem formula iz trećeg poglavlja. Uravnoteženje masa provedeno je protuutegom na svakom koljenu, kojim su uravnotežene centrifugalne sile, i translacijske sile prvog reda. Izračun sila drugog reda, obavljen je kao dodatni potencijal za smanjenje opterećenja na mehanizam motora. Kao rezultat analize dobiveni su polarni dijagrami svih glavnih ležajeva motora i osnaca koljena koljenastog vratila.
Abstract (english)
This paper deals with a load analysis of diesel V8 engine crank mechanism. Engine power gains 720 kW at 1600 rpm. The main description of work is given in first two chapters. Main characteristics of engine are given in the third chapter. Mass balancing formulae and solving kinematics and dynamics of mechanism is given in fourth chapter. Load analysis is performed by MS Excel with usage of formulae from fourth chapter. Mass balancing is solved with counterweight on each of a throw. With the same counterweight there have been balanced centrifugal forces, and first order inertial forces. Aditional potential for decreasing load on mechanism, have been made by calculation of second order inertial forces. As a result of analysis, load characteristic have been made for all main crankshaft bearings and a journal of each throw.
